The recommended install procedure for these OS's is to uninstall any previous versions of Qube, along with the GUI, supervisor, and worker, and then open a command prompt with "elevated privileges" (Microsoft's term) by rt-click "Run as Administrator". From this "privileged" command prompt, perform the install with the msiexec utility:

Code:msiexec /i <path_to_msi_file>

Do this for each of the Qube components that you need to install on the machine in question.
